MAKING THE CONNECTIONS
The projector may be connected to different equipment. The following
sections describe in detail how to connect to these systems.
See the illustration on the rear of the quick set-up card on how the various
system parts connect together.
Be aware of static electricity that may build up in the dry season and when
operating on synthetic carpets. Discharge any static electricity by touching a
metallic surface before you start.
Place the projector on a table at a suitable distance to the projection
screen. Select a screen with good reflectivity and avoid direct sunlight
shining in. Place the projector so that the image is visible to the whole
audience, and so that the unit does not obstruct the view. The projector is
supplied with long cables for high flexibility in placement.
Various cables are supplied or optionally available to connect to different
sources. Follow the list below in numerical order for a trouble-free set-up!
1. SWITCH OFF all equipment before making all the connections.
2. COMPUTER GRAPHICS ADAPTER.
Computer graphics adapters use different connectors depending on the
actual computer system in use. Connection to the projector is made
through a basic GA cable and appropriate adapters.
• PC. Use the GA cable directly to connect the graphics port of
the PC to the COMPUTER connector on the projector. If
needed, connect your monitor cable to the free branch on the
GA cable.
• MAC. Use the MAC adapters, as marked, on the computer end
of the GA cable to adapt to the graphics-port connector and
monitor connector on the MAC.
• NEC. Use the optional NEC adapters, as marked, on the
computer end of the GA cable to adapt to the graphics-port
connector and monitor connector on the NEC.

USER GUIDE
SVGA LCD PROJECTOR
3. SOUND.
The GA cable has a sound input branch at the projector end. Connect
sound from the computer using a standard 3.5 mm stereo jack line cable
(not supplied).
4. MOUSE.
To enable mouse control from the remote control, a connection is made
using a mouse cable and various adapters. Connect the cable directly to
the MOUSE connector on the projector. Connect the appropriate
adapter to the free end of the mouse cable at the computer end as
described below.
• SERIAL (RS 232). Use the serial adapter with a branch for the
local computer mouse. The serial adapter is fitted with a 9 pin
DSUB connector. Use an extra 9 to 25 pin adapter (available
from your dealer) if your computer has a 25 pin serial
connector. Connect your computer mouse to the free branch of
the adapter if desired. With some computers, the branched
adapter may not work. For this purpose, an optional straight
serial adapter is available.
• PS/2. Use the PS/2 adapter that connects directly to your
computer mouse port. Running the computer mouse in parallel
is not possible, unless your computer itself has provision for
two mice simultaneously. You may consider using the above
serial adapter and run your mouse on the serial port instead, in
order to be able to run your local mouse in parallel. This will
require a different mouse driver setting. Please consult your
computer documentation or local dealer for details.
• MAC. Use the MAC mouse adapter to connect to the mouse
port on your MAC computer.
5. MAINS POWER.
Connect the mains cord to the projector and all other equipment in the

IMAGE ADJUSTMENTS
This section will aid in adjusting a stable, flicker-free image for best viewing
results.
Use the remote control or the projector keypad to adjust settings, either
directly or through the menu system.
The following list aids in a trouble free set-up of the projector. Try using a
patterned background (tiles, checkerboard pattern etc) when adjusting the
image.
1. ZOOM, FOCUS AND POSITION IMAGE. The projection lens has a
manually adjustable zoom and focus. Place the projector at a suitable
distance to the projection screen, alternatively zoom the image, to
obtain the desired screen size. (See the Technical Data section for max
and min projection distances.) Focus the image and observe that the
picture elements (pixels) become sharp on screen. The projector has
two adjustable feet in the front, so that the image can be shifted to a
desired height on the wall. Tilt the projector body in the desired position
and press the foot-release buttons. If necessary, fine adjust the height
by screwing the feet either direction.
2. RESET in most cases automatically adjusts the image position, width
(FREQUENCY) and stability (TUNE). If RESET fails to adjust the image
correctly, see FREQUENCY, POSITION and TUNE below. RESET is
automatically activated when a new source is connected.
3. SCALE the image as desired if you are viewing a lower (VGA) or higher
(XGA) resolution image. Scaling will fill the viewable area by enlarging a
lower resolution or compressing a higher resolution image. If you do not
14
USER GUIDE
SVGA LCD PROJECTOR
scale a higher resolution image, you may choose to PAN around instead
in order to view parts of the image.
4. CONTRAST and BRIGHTNESS may be adjusted according to your
personal taste, the image and the viewing conditions. The controls are
directly accessible on the remote control and on the projector keyboard.
5. FREQUENCY. The frequency controls the width of the image. A wrong
frequency setting can be seen as equally spaced, vertical stripes or
irregularities in the pattern displayed. Press the MENU key, SET-UP,
FREQUENCY and press ENTER. Adjust the value up or down using the
trackball or keyboard cursor controls, observing that the amount of
vertical stripes reduces, until the distortion is gone. You may still have
an unstable image, please see the next section.
6. POSITION the image correctly by accessing SET-UP, POSITION, then
press ENTER and adjust position with the trackball or keyboard cursor
controls
7. TUNE the image for a stable projection. In the menu, select SET-UP,
TUNE and press ENTER. Adjust stability using the trackball.
Set-up should be done once with the source(s) you are using most
frequently. Allow some minutes for the unit to warm up before adjusting the
settings. Most settings will be memorized individually for each source for
future use.

CEILING MOUNTING
The projector is prepared for ceiling mounting. As opposed to desktop use
(most tables are approx. 80 cm tall, are flat and have a hard surface finish),
ceilings vary in height and material. Also considerations must be made with
respect to signal and power wiring.
9.1
SELECTING A MOUNT
100
200
Various mounting systems are available from different sources. Contact
your dealer for further details or consult vendor catalogs. Be sure that the
vendor has tested the mount with this specific projector for operational
safety. Check that the mounting brackets fit the integral M4 screw mounts
(see illustration below) of the projector, and that the ventilation slots are not
blocked.

USER GUIDE
9.2
SVGA LCD PROJECTOR
MOUNTING IN THE CEILING
An improperly mounted projector is a potential danger to
people and equipment. A projector and mount falling down
may cause personal injury and material damage. Such
damage caused by bad workmanship in mounting and
operation may lead to legal action and should be avoided.
Avoid ceiling mounting of the projector in areas of frequent
or probable earth quakes.
When fixing the mount in the ceiling, be sure to check the ceiling material
and if it will hold the total weight of the mount and the projector. Look for
wood, steel beams or concrete that will secure a good and lasting fixture.
Avoid plaster or other fragile materials that do not have sufficient structural
properties. Follow the detailed instructions supplied with the ceiling mount
for proper mounting and operation.
After having mounted the projector in the ceiling, test if the holding force is
sufficient by adding a load to the mount at least double the weight of the
combined projector and mount. The mount should hold this extra weight
with no sign of fatigue and with no sign of mounting screws loosening.
9.3
WIRING
Ceiling mounted projectors require long signal and power wires.
The signals should be wired using high quality coaxial cable. The cables
usually need to be customized. Some vendors have specialized in this field.
Contact your dealer for further detail.
If the signal cables run over a longer distance from the source to the
projector, a line buffer (distribution amplifier) may be needed (available from
third party vendors).
For potential fire reasons, the power wiring should be
separately switched so that the projector can be switched off
completely when not in use. The ON/OFF on the remote
control only suspends operation of the projector without
switching off completely.

10 YOUR PROJECTOR IN DETAIL
The projector is designed from the ground up to be a compact, durable,
bright and versatile device that is suitable for use in various indoors
projection applications.
International mandatory regulations are employed, including the rigorous
European CE and American UL and FCC standards that cover safety and
radio interference issues.
Product packaging is by environmentally friendly materials that are
recyclable and that do not emit any toxic fumes if combusted. The ‘RESY’
and ‘Grüne Punkt’marks are referenced (with ID numbers), indicating that
the proper fees are already paid for controlled return of packaging material.
The projector powers down according to the latest standards to minimize
power consumption when the source connected becomes inactive (by lack
of activity or when the source is switched off). Operation is automatically
resumed when the source again becomes active, though some delay is
incurred when restarting the projection lamp.
To allow for flexible operation and installation, the unit may be operated
from the tabletop, ceiling mounted or in a rear-projection arrangement. Safe
thermal operation is secured through a temperature controlled, well
dimensioned cooling system that is minimizing fan noise and stray light.
Compatibility is wide, including most popular computer sources from VGA
(640x480 expanded) to XGA (1024x768 compressed) resolution.
A wide mains voltage operating range is employed, and connection is
through the internationally recognized IEC connector. The menu system is
multi-lingual.
The following chapters detail various features of your projector that may be
of interest.

USER GUIDE
10.1
SVGA LCD PROJECTOR
SLB - SMALL, LIGHT AND BRIGHT
The projector was designed to be the ultimate portable projector.
The advanced, miniaturized optical design and the use of a relatively low
power, high efficiency illumination system combined with optimalized
electronics has yielded a very compact, lightweight projector.
10.2
AUTOMATIC SETUP
The projector always seeks to adjust the projected image automatically. The
user may also at any time invoke the autoadjust function by pressing
RESET. When auto is operating, the image will be shifted to different
positions on screen for about 5 seconds before it is stabilized.
10.3
POLYSILICON TFT LCD TECHNOLOGY
The light valve technology employed in the projector is based on small TFT
(Thin Film Transistor) LCDs (Liquid Crystal Displays) manufactured in a
high temperature process enabling the formation of so called PolySilicon
transistors. These transistors are used both as switching elements at each
picture element (pixel), and for other electronic signal handling.
10.4
BASIC OPTICAL SYSTEM
The projector is based on three PolySilicon TFT LCD light valves, one each
for the primary red, green and blue colors of the spectrum. Any other color
may be produced by combining various amounts of these primary colors.
High brightness is made possible by novel techniques for improved light
collection in the illumination system and better distribution through the
optical system. A special PBS (Polarized Beam Splitter) is employed to
reduce the traditional loss of light that is normally associated with LCD
systems using polarized light.

distribution. The white light is then split by dichroic mirrors in three rays of
the primary colors red, green and blue. These beams are then directed to
one each of the three LCD valves. Depending on the control of these three
LCDs, where each primary component of the image is separated, light is let
through or blocked. The beams are then recombined in a prism and
directed to the projection lens.
The projection lens has zoom and focus rings available to the user in order
to be able to select a suitable magnification (image size) at a given
projection distance, and to adjust for a sharp image.
10.5
TRACKBALL REMOTE CONTROL
The remote control enables both set-up of the projector and control both of
the projector and the computer mouse pointer during operation.
The mouse functionality duplicates the local computer mouse without the
need for any special software drivers.
10.6
MENU SYSTEM
The menu system is designed so that it may be invoked and overlayed at
any time with any image projected. When invoked, the menu system will not
interrupt the display of the underlying image. The hierarchical design, with a
main menu and sub-menus, provides a logical approach to access the
various functions. The localization in the upper left corner and the moderate
size of the menus does not block much of the view of the image displayed.
Several languages are selectable to suit international users from east and
west.
10.7
OSD SYSTEM
The OSD (On Screen Display) is used to echo user controls for positive
feedback. The OSD is active both within the menu and with direct controls.
The OSD should not be confused with the menu system, the latter being
used to gain access to controls, while the OSD merely indicates the actual
operation. The OSD may be selected or deselected in the menu.
10.8
SET-UP MEMORY
The various user selections and settings that are made with the remote
control, the projector keypad and the menu system, are automatically
memorized for future reference. Most settings are related to the actual
source in use, so when switching between sources, or between modes
within sources, the individual settings are recalled accordingly.
29
USER GUIDE
SVGA LCD PROJECTOR
The memory can store up to 40 different sources and mode characteristics.
Some sources are predefined, while the remaining are available for
customer set-up. See the compatibility list in the Technical Data section.
New sources are added to the memory only if the sync pattern differs
significantly from a previous selection. If a new source is detected as an old
one (close or identical sync patterns), and the settings are changed, the
new settings will override the old ones.
See the Remote Control and Menu sections for details of which functions
that are memorized.
10.9
COOLING SYSTEM
The heat generated in the projection lamp and in the electronics circuitry
needs to be effectively vented out of the projector. Cooling fans are
employed to force the convection of air through the system. Air is let out
close to the projection lamp (as this is the hottest area).
The projector is designed to operate at a wide temperature range and works
well when ceiling mounted, even at high ambients. See the technical Data
section for temperature specification.
The cooling system is temperature controlled, so that when operated on the
desktop at normal temperature, the noise level is minimized due to a
relaxed fan speed. When operating in the ceiling under high temperature
ambients, the fan runs at a higher speed to maintain cooling while the noise
level increases. The light leakage out of the vents is minimized by a special
light blocking design of the vent flanges.

11 APPLICATIONS
The projector is perfectly suited for a variety of different applications
including portable use, work groups, teaching, training, home theatres,
control rooms, product promotion, shows, simulators and more…
11.1
PORTABLE USE
The projector is designed with portability in mind for the nomadic user. The
footprint is small and the weight is low. The unit is employed with an integral
handle, and is supplied with a soft carrying case holding the projector and
all cables. The unit can be carried on-board an aeroplane and fits easily in
the overhead locker. Remember that the projector is a delicate instrument
containing precision optics. Avoid bumping and dropping the unit during
transportation. When checking the unit in at the airport, ensure proper
packaging to avoid breakage and malfunction. It is wise to bring an extra
projection lamp, just in case…
11.2
WORK GROUPS
A work group typically involves a group of people actively involved in
discussions round the table. The projector usually is connected to a
networked computer. As the meeting evolves, various documents are
continuously updated and corrected. Information is downloaded from the
Internet or the company Intranet for up-to-date processing in the group. By
the end of the session, the documents are wrapped up and minutes are
distributed to the various recipients over the e-mail system. The projector
may be placed on a table or permanently installed, either ceiling mounted or
arranged for rear projection.
11.3
TEACHING
Educational institutions would use the projector both for traditional computer
based teaching for the class, as well as interactive use over the Internet. By
using the projector, the attention of the students is focused on a single large
projection screen, supplementing the ordinary, individual computer monitors
when needed. The projector may be placed on a table or permanently
installed, either ceiling mounted or arranged for rear projection.
31
USER GUIDE
11.4
SVGA LCD PROJECTOR
TRAINING
The projector is ideally suited for company training in various areas such as
products, software, organisational and staff continued education. It is
practical for this purpose to have a dedicated training room with good
facilities for each individual in order to secure the attention of each person
during the training session. The projector may be placed on a table or
permanently installed, either ceiling mounted or arranged for rear
projection.
11.5
CONTROL ROOMS
Large screen projection of critical information enables a quicker and more
consistent reaction to any change that needs immediate attention. This
includes both manufacturing process control, as well as operational control
in private, public and military situations. Several projectors may be
cascaded or grouped to simultaneously project over a larger area or to
project different screens simultaneously, using a dedicated screen splitter
(available from third party suppliers). These applications are typically fixed
and the projectors are usually either ceiling mounted for front projection or
arranged in a rear-projection set-up.
11.6
PRODUCT PROMOTION
The projector is ideally suited to attract attention in order to promote sales
of all kinds of products in shops and malls. The promotion material may be
either computer generated based. Several projectors may be employed
simultaneously to increase attention further. The projector is usually semipermanently installed, either ceiling mounted or arranged for rear
projection.
32
USER GUIDE
11.7
SVGA LCD PROJECTOR
TRADE SHOWS
Many companies attend various trade shows throughout the year. In these
situations, the key issue is to attract the attention of a large, continuously
moving public. One or more units projecting your company message will
help steering the crowd to your business. The projector might be either
placed on the table top, ceiling mounted or used for rear projection. Since
control over lighting conditions is difficult at trade shows, arranging two
projectors on top of each other projecting, the same image on the same
screen will help by increasing the brightness.
11.8
SIMULATORS
Simulators are used in various applications for training and entertainment.
Professional use includes car driving, air plane and ship vessel control
training, as well as other expensive and often dangerous situations that
require well trained personnel. Entertainment use is basically in various
theme parks etc.

13 MAINTENANCE
The projector needs very little maintenance in order to function properly.
13.1
GENERAL
Use a damp cloth to wipe off dust on the exterior. Clean the lens with a
damp, non-abrasive cloth, using just water or a standard lens cleaning
solution available from photographic dealers.
Vacuum the air inlets periodically, especially when build-up of dust is
observed. This will ensure cool operation of the unit.
Do not scratch the lens surface. Use the lens cap when the projector is not
in use for added protection. Remember to remove the lens cap before
operating the unit!
13.2
LAMP REPLACEMENT
The projector is using a custom metal halide lamp for illumination. The lamp
is high pressure when hot (operating or immediately after switch-off). Lamp
pressure is normal when cold.
A lamp timer is available in the menu system under HELP, ABOUT, that
may be used to track lamp operating time. The timer may be reset by the
user.
